The lite create/open/restore requests carried a passphrase field that the UI collected
(a labeled, masked "passphrase" input) but the backend initialize* calls never used —
so a user could believe their lite wallet was passphrase-protected at creation when it
did nothing. It now has a real meaning, wired in LiteWalletController:
- create / restore -> encryptWallet(passphrase): the backend encrypts + locks + saves
the brand-new wallet.
- open -> unlockWallet(passphrase), but only when encryptionStatus() reports the existing
wallet is actually encrypted + locked (no spurious unlock on an unencrypted wallet).
encryptWallet/unlockWallet take their own copy of the passphrase and wipe it; the
request copy is still wiped as before. A post-create encrypt failure is liteLog'd (the
wallet still exists, so the create is not failed).
Six existing lite-controller tests carried an incidental "hunter2" create passphrase from
when the field was dead; removed (they exercise non-encryption flows and want an
unencrypted wallet), and added testLiteWalletControllerCreateEncryptsWithPassphrase to
prove the new behavior. Completes the wallet-hardening P0-A cluster (7/7). ctest 1/1.
